1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundRetinal pigment epithelium (RPE) 65 is a key enzyme in the visual cycle involved in the regeneration of 11-cis-retinal. Mutations in the human RPE65 gene cause Leber's congenital amaurosis (LCA), a severe form of an inherited retinal disorder. Animal models carrying Rpe65 mutations develop early-onset retinal degeneration. In particular, the cones degenerate faster than the rods. To date, gene therapy has been used successfully to treat RPE65-associated retinal disorders. However, gene therapy does not completely prevent progressive retinal degeneration in patients, possibly due to the vulnerability of cones in these patients. In the present study, we tested whether leukemia inhibitory factor (LIF), a trophic factor, protects cones in rd12 mice harboring a nonsense mutation in Rpe65.

methodsLIF was administered to rd12 mice by intravitreal microinjection. Apoptosis of retinal cells was analyzed by TUNEL assay. The degeneration of cone cells was evaluated by immunostaining of retinal sections and retinal flat-mounts. Signaling proteins regulated by LIF in the retinal and cultured cells were determined by immunoblotting.

resultsIntravitreal administration of LIF activated the STAT3 signaling pathway, thereby inhibiting photoreceptor apoptosis and preserving cones in rd12 mice. Niclosamide (NCL), an inhibitor of STAT3 signaling, effectively blocked STAT3 signaling and autophagy in cultured 661W cells treated with LIF. Co-administration of LIF with NCL to rd12 mice abolished the protective effect of LIF, suggesting that STAT3 signaling and autophagy mediate the protection.

conclusionLIF is a potent factor that protects cones in rd12 mice. This finding implies that LIF can be used in combination with gene therapy to achieve better therapeutic outcomes for patients with RPE65-associated LCA.
